Bridge USDC to your Arbitrum Rollup

Use the Recommended Bridging Method
To bridge your USDC, follow the official Arbitrum Token Bridge documentation.
Migrating Existing USDC Liquidity to Circle’s USDC Standard
This guide applies only to USDC bridged in via the standard gateway. If your USDC was bridged using third-party bridges such as LayerZero or Wormhole, it cannot be easily migrated.
Users will need to migrate their existing liquidity manually. We’ve created a guide to help facilitate this process that you can share with them. To complete the migration, users will need access to your old Standard Gateway address. Follow these steps to locate it.
1. Sign In
Log in to the Conduit app.
2. Access the Rollup Deployment Dashboard
In your deployment dashboard, go to the Overview section, and find core.json in the bottom right corner.
3. Locate the Standard Gateway Address
Within core.json, locate the standardGateway. Then, navigate to your Settlement Layer’s block explorer and check for the counterpartGateway under Contract -> Read as Proxy.
4. Provide the Gateway Address and Guide to Users
Share the standardGateway address with your users, along with the following guide: User Guide: Migrating Existing USDC Liquidity to Circle’s USDC Standard
